What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Because of the advantages of anthocyanins, the genetics and breeding of crops rich in anthocyanins has become a hot research topic. However, due to the lack of anthocyanin-related mutants, no regulatory genes have been mapped in Brassica napus. In this study, we first report the characterization of a B. napus line with purple leaves and the fine mapping and candidate screening of the BnaA.PL1 gene. The amount of anthocyanins in the purple leaf line was six times higher than that in a green leaf line. A genetic analysis indicated that the purple character was controlled by an incomplete dominant gene. Through map-based cloning, we localized the BnaA.PL1 gene to a 99-kb region at the end of B. napus chromosome A03. Transcriptional analysis of 11 genes located in the target region revealed that the expression level of only the BnAPR2 gene in seedling leaves decreased from purple to reddish green to green individuals, a finding that was consistent with the measured anthocyanin accumulation levels. Molecular cloning and sequence analysis of BnAPR2 showed that the purple individual-derived allele contained 17 variants. Markers co-segregating with BnaA.PL1 were developed from the sequence of BnAPR2 and were validated in the BC4P2 population. These results suggested that BnAPR2, which encodes adenosine 5'-phosphosulfate reductase, is likely to be a valuable candidate gene. This work may lay the foundation for the marker-assisted selection of B. napus vegetables that are rich in anthocyanins and for an improved understanding of the molecular mechanisms controlling anthocyanin accumulation in Brassica.
